Question

Which point lies on the $x-$axis?

• A. $\left(0,3\right)$
• B. $\left(-3,0\right)$
• C. $\left(4,-3\right)$
• D. $\left(-5,-1\right)$

Answer 1

The correct option is B

$\left(-3,0\right)$

Step 1. Explanation for the correct option.

Any point on the axis is of the form $\left(a,0\right)$. Here, the $x$coordinate is $a$ and the $y$ coordinate is $0$.

So, from the above options the point $\left(-3,0\right)$ lies on the $x-$axis.

Step 2. Explanation for the incorrect options.

All the other options are incorrect as their $y$ coordinate is not $0$.

Hence, the correct option is $\mathrm{B}$.
